Dear Sahil, the DCM for fNIRS code is written by Sungho Tak and available in SPM12 in the folder: spm12/toolbox/dcm_fnirs It is possible that you need to use the SPM for fNIRS toolbox in order to get your data in the right format: https://www.nitrc.org/projects/spm_fnirs/ The NITRC forum might be the best place to get help related to this toolbox.
